Long time fan favorite. The Karma is available in a variety of sizes to be used in almost any condition. Dual Tread Compound. The ultimate tread compound. Kenda's L3R PRO compound (60 shore A durometer) in the center and the cornering knobs have STICK-E compound (50 shore A durometer). The benefits are great center tread life, and great cornering control and grip. Found typically in Kenda's Legends Series and race/performance tires. L3R Pro An upscale version of L3R blended together with Kenda's high performance Motorcycle Rubber Compounds. Benefits are extended tread life and a lighter tire. Typically found on Kenda's high performance cross country (XC) mountain bike tires and road tires.
